Quiznos filed a so-called prepackaged bankruptcy, which means it has already secured key creditors’ support for a restructuring plan. Such plans allow for speedier and cheaper Chapter 11 proceedings.

Quiznos’s senior lenders, which the company said have voted in favor of its restructuring plan, have also offered $15 million to finance the company’s restructuring.

The financing and restructuring plan will be subject to the approval of the U.S. Bankruptcy Court in Wilmington, Del., where Quiznos’s parent and affiliates filed their own separate Chapter 11 petitions.

The detailed of the restructuring plan are still to come — we’ll take a look at the court documents once they’re available — but going into Chapter 11 will give Quiznos a chance to renegotiate leases and other contracts. With most of its stores operated by franchisee owners, Quiznos isn’t sitting on a giant portfolio of company-run real estate like Sbarro is, but it does sell ingredients and other supplies to the franchised stores.

The cost of those supplies was a major point of dispute that led the company into conflict with many of its franchisees, and resolving those disputes will be a big part of any plan to get the company back on its feet.

Sbarro also went into prpackaged bankruptcy, with a restructuring plan pre-approved by 98% of its lenders, although the pizza chain is also pursuing an auction process to see if anyone might want to buy the company. The pizza, like the sandwiches, will live on.
